Quantum physics once shocked scientists by revealing that particles can behave like waves—and now, that strange behavior has been pushed even further. For the first time, researchers have observed ...

Positronium shouldn’t last long enough to be interesting. It’s an “atom” assembled from an electron and its antimatter twin — a positron — locked in orbit around each other, destined to destroy ...

It seems like the stuff of science fiction, but NSF-sponsored researchers working at CERN, the European Organization for Nuclear Research, have probed the properties of whole atoms of antimatter, the ...

Scientists studying the tracks of particles streaming from six billion collisions of atomic nuclei at the Relativistic Heavy Ion Collider (RHIC) -- an 'atom smasher' that recreates the conditions of ...

Up next, another installment in the continuing quest to understand antimatter, that stuff that's supposed to be the opposite of matter. It's supposed to have been created during the Big Bang in equal ...

Researchers at Tokyo University of Science have, for the first time, observed quantum interference in a beam of positronium — an exotic atom made of an electron and its antimatter twin, the positron.
